The locking force is rated at 2600 N, which means it resists forced opening of a guard door up to that load, meeting the requirements of EN ISO 14119 for interlocking devices on machinery. This is not a spring-latch mechanism; the magnetic lock provides positive holding without mechanical wear on a latch, making it suited for high-cycle guarding applications where a solenoid release is preferred over a manual pull. The switch accepts 5 directions of approach for the separate actuator (sold separately — the 3SE5000-0AV0 is the compatible actuator for this family), giving flexibility in mounting orientation on sliding, hinged, or lift-off guards. The housing is metal with cathodic dip coating, rated IP66/IP67, so it withstands washdown environments and outdoor installation without corrosion issues. ## Electrical ratings and connection The solenoid coil runs on 24 V DC. The switch contacts are slow-action (not snap-action), rated at 10 A thermal current (Ith) with an insulation voltage of 250 V. Switching capacities vary by voltage: 6 A at 120 V AC, 3 A at 240 V AC, 3 A at 24 V DC, and lower ratings for 125 V DC (0.55 A) and 250 V DC (0.27 A). The screw terminals accept 1x (0.5 to 1.5 mm²) or 2x (0.5 to 0.75 mm²) solid conductors, with three cable entries of M20 x 1.5. Shock resistance is 30g for 11 ms, vibration resistance is 0.35 mm at 5g, both tested per IEC 60068-2-27 and IEC 60068-2-6. Repeat accuracy of 0.05 mm ensures consistent actuation point over the life of the switch.","metaTitle":"Siemens 3SE5312-0SB11 Safety Position Switch","metaDescription":"Siemens SIRIUS 3SE5312-0SB11 mechanical safety switch with magnetic lock, 2600 N holding force, IP66/IP67.
